Pay attention to the spindle motor of the woodworking engraving machine. The spindle motor is an important component of the computer engraving machine, and its performance has an important influence on the performance of the computer engraving machine. Machining spindles are generally divided into two categories: precision machining spindles and high power cutting spindles.
1. The characteristics of the fine machining spindle are low noise, high speed and height, suitable for processing particularly fine workpieces such as stamps, nameplates, badges and so on. Such motors are usually high-speed variable frequency motors with low power, typically below 250W. The disadvantage is that the ability to cut thick materials is poor and does not cut off thicker materials.
2, high power cut off the spindle, mainly used for cutting, high power engraving, characterized by high power, strong cutting ability, especially suitable for cutting the universe, three-dimensional characters, of course, you can also make badges, nameplates, seals and so on. Such high-power spindles can be generally divided into brushless high-speed AC motors and brushed AC motors according to the characteristics of the motor. The main difference is: A, the brushless inverter motor has a high speed, and the shift range is 70060000 rpm, and generally there are Brush AC motor Highest speed does not exceed 24000 rev / min: B, brushless inverter motor has high rotation precision, low wear and low noise, making noise much lower than brushed AC motor; C, brushless inverter motor stalling characteristics are good, due to There is a special current limiting circuit on the inverter. The short-time blocking will not burn the motor, and the brushed AC will burn out quickly when it is overloaded or blocked, and it cannot be repaired. D. Brushless inverter motor It adopts frequency conversion control technology to adjust the speed. It is a professional-grade product with long service life. The manufacturer provides one-year free replacement. In the future, the motor can be maintained by replacing the high-speed bearing. The brushed AC motor has a life of about 300 hours. The motor or motor carbon brush has to be replaced, so the carbon brush AC motor is usually not guaranteed for one day.
